HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 411,541, datedSeptember 24, 1889.

' Application filed March 8, 1888. Serial No. 266,499. (No model.)

T0 @ZZ whom it may concern.-

Be it known that we, LEWIS ACHOR and ToBIAs HAMILTON, citizens of theUnited States, residing at Martinsville, in the county of Clinton andState of Ohio, have invented a new and useful Improvement in HeatingApparatus, of which the following is a speciiication.

Our invention relates to an improvement in heating apparatus; and itconsists in the peculiar construction and combination of devices thatwill be more fully set forth hereinafter, and particularly pointed outin the claim.

In the accompanying drawings, Figure l is an elevation of a heatingapparatus embodying our improvements. Fig. 2 is a vertical sectionalview of the same, taken on the line of Fig. l. Fig. 3 is a detailperspective view of the heating-drum and oven, with parts broken away todisclose the interior construction of the same. Fig. 4 is a horizontalsectional view of the same, taken on the line y y of Fig. 3.

A represents a heater, which is arranged in the form of a rectangularbox, is made, preferably, of cast Inetal, and is adapted to iit snuglyin a fire-place. The front side of the said heater is open, and theupper'side of the heater is shaped like an inverted funnel, and isprovided with a pipe B, which extends up the chimney. In the heater isarranged a grate C, thereby forming a iire-box D above the grate, and anash-pit E below the same.

F represents a damper, which is arranged in the heater at a suitabledistance above the grate.

G represents a drum, which is rectangular in shape and is located in thechimney in an upper apartment. The said drum comprises an outer case orshell H and an inner case or shell I, which latter shell is locatedwithin the outer shell and at a distance from the sides thereof, therebyforming a flue or space K, which entirely surrounds the inner shell. Theupper side of the inner shell is inclined in opposite directions, toprevent soot from accumulating thereon. The front side of the drum isopen, and communicates with the apartment with which it is located, andis provided with a removable or hinged door L. 0n the vertical sidewalls of the inner shell are secured cleats M, which are adapted tosupport grates N, thereby adapting the drum to be used as an oven forheating or cooking food. The upper end of the pipe B communicates withthe lower side of the drum, and the upper side of the said drurncommunicates with the chimney or iiue, being provided with an opening Ofor this purpose.

The operation of our invention is as follows: The heat and products ofcombustion from the iire pass upward through the pipe B into the tlue orspace K of the drum, circulate around the inner shell or face thereofand heat the same, and then escape through the opening O up the chimneyor ue to the outer air. The air within the inner case or shell is heatedby radiation, and when the door L is opened escapes into the room inwhich the drum is located. The said door may, if preferred, be made inthe form of a register. When the door is closed and the grates are thenplaced in the inner shell of the drum, the same is adapted to be used asan oven for heating or cooking food.

By means of our invention, hereinbefore described, we are enabled toutilize the heat which is ordinarily wasted and escapes up the chimneyto heat an upper apartment and to heat or cook food.

Having thus described our invention, we claim--n A domestic heatingapparatus or oven comprising a rectangular drum or casing embedded in achimney in an upper apartment of a building or dwelling-house, an oveninclosed by the said drum, except at the front, where it is providedwith a door, said oven having slanting upper sides that meet so as toform a longitudinal ridge at the top thereof, a flue connecting anopening in the lower side of the drum or casing with a tire-place in alower apartment of the building7 and an exit-opening in the uppes sideof the drum or casing communicating with the upper chimhey-flue,substantially as set forth.

In testimony that we claim the foregoing as our own we have heretoatlixed our signatures in presence of two witnesses.
